The MariaDB Plugin API has Doxygen Documentation Now!
Developing plugins is one of the ways we really encourage to extend MariaDB Server’s capabilities. However, understanding the available APIs has often required developers to explore header files, source code, and existing plugin implementations.To make this easier, we now have a new, Doxygen-generated MariaDB Server Plugin API reference, available directly in the MariaDB documentation.If you’ve been following recent commits to the MariaDB Server repository, you may already have noticed some of the work behind this initiative. I’d like to present […]

What MariaDB’s plugin API can carry: the HyperLogLog case
Can a complete analytic feature live outside the MariaDB server core? By “complete” I mean a column type, aggregates that build its values, and scalar functions that read them. I built the type_hll plugin, which adds HyperLogLog sketches to MariaDB, and I use it here to answer that question.
The answer is mostly yes. One shared library, type_hll.so, registers the HLL data type and eight functions. You enable all of it with one statement:
The “mostly” is important. The HLL […]

Laravel 13 now supports MariaDB Vector natively
If your Laravel application runs on MariaDB, you can add semantic search to it without a second database, an external vector service or an extra package. Since Laravel 13.28, vector columns, vector indexes and similarity queries work on MariaDB out of the box. A large part of that work came from community contributors, including Mohamed Touhami Rhaima.
Until this summer, Laravel’s built-in vector search was a PostgreSQL feature: it assumed pgvector. Laravel’s AI SDK documentation now reads: “Vector queries are currently supported on […]

From a Chocolate Wrapper to Concurrent InnoDB Page Splits
This work started from a conversation with Monty Widenius at Meet Magento Czech in August. We discussed possible ways to improve the scalability of the InnoDB B+Tree, especially its insert path and page splits.
Monty explained several ideas about reducing synchronization during structural changes and allowing independent parts of the tree to make progress concurrently. We did not have a whiteboard, so we made the first design sketch on the back of a dark chocolate wrapper.
The sketch contained a […]

From a Production Problem to MariaDB: Headout’s Open-Source Contribution Journey
A production bottleneck at Headout led to a new MariaDB Server improvement. This is the story of how engineers, maintainers and AI-assisted development turned a real-world problem into an upstream open-source contribution.

MariaDB 13.1 Feature in Focus: BLOB, TEXT, JSON and GEOMETRY Support in the HEAP Engine
Some contributions improve MariaDB Server by adding new capabilities.
Some go further: they start from a concrete production problem with an existing feature, not a bug, but a design limitation, solve it upstream, and leave the whole ecosystem better off.
This is one of those contributions.
The platform team at Headout, a global platform that helps travelers discover and book curated real-life experiences, encountered a few inefficiencies in MariaDB Server around temporary tables and the HEAP engine. Instead of treating […]

MariaDB 13.1 Feature in Focus: DENY / Negative Grants
MariaDB 13.1 Preview is full of nice things.
Some are immediately visible to developers, like the new JSON operators. Some are very useful to DBAs, such as configuration validation. And some are about making security and access control easier to manage.
Today, let’s look at one of those: DENY, also known as negative grants.
Yes, negative grants.
It sounds a bit strange the first time you hear it, but the idea is very simple:
Sometimes it is easier to say […]
